This is like saying the technicians who is in charge of TriMet's radio (dispatch) system should also be in charge of creating TriMet advertisements for the FM dial.

The job for these folks is to make sure TriMets computers stay running and to create/maintain software tools that help TriMet to do its job.

Ex: they create the tools that the schedule writers use, but they don't write the schedules themselves. They create the systems for dispatch, AVL, stop announcements, trip planner, etc - but they are not dispatchers.
